I bought the CM690 from a local retailer who I had a gift card for this past weekend. I also noticed this online:
Canada Computers - LCD Monitors > Open Box/Refurbished : Acer X243WBD Widescreen LCD Monitor - 1920 x 1200, 5ms, 400cd/m2, 3000:1 DCR, VGA/ DVI-D (Factory Refurbished). It is factory refurbished, but are you going to find a 24" LCD for that price anywhere? Even with MIR or one-time deals?
